There is a python proxy included 92('websockify'). 93 94 95### Quick Start 96 97* Use the launch script to start a mini-webserver and the WebSockets 98 proxy (websockify). The `--vnc` option is used to specify the location of 99 a running VNC server: 100 101 `./utils/launch.sh --vnc localhost:5901` 102 103* Point your browser to the cut-and-paste URL that is output by the 104 launch script. Enter a password if the VNC server has one 105 configured. Hit the Connect button and enjoy! 106 107 108### Other Pages 109 110* [Encrypted Connections](https://github.com/kanaka/websockify/wiki/Encrypted-Connections).
